O'VERH EAD REG'ENERATIVE GAS-LAM P.

SPECIFICATION forming part of Letters Patent No. 682,896, dated September 17, 1901. Application filed April 5, 1901. Serial No. 64 505. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM HENRY ISAAC WELCH, a citizen of England, residing at 68 Coborne road, Bow, in the county of London, England, have invented a certain new and useful Improvement in Overhead Regenerative Gas-Lamps, (for which I have obtained a patent in Belgium, dated September 19, 1900, No. 152,135 ;in France, dated September 18, 1900, No. 303,864, and in Great Britain, dated September 18, 1900, No. 16,626,) of which the following is a specification.

I This invention relates to overhead gaslamps in which the flame is supplied with air heated by passing through channels the walls of which are heated by the passage of the hot products of combustion from the flame.

I shall describe my invention, referring to the accompanying drawings, which show a lamp suited for fixing to the ceiling of a railway-carriage compartment.

Figure 1 is a Vertical section of a lamp according to my invention, the external chimney and wind-guards, which'form no part of my invention, being shown in outline. Fig. 2 is a plan on the line 2 2 of Fig. 1.

The main inlets c for the air to supply the flame and the central outlet b for the products of combustion to the chimney n are formed in a casting a, which, as well as the flangef of the glass 9, is carried on a lip inwardlyprojecting from a flanged ring l,'which is fixed to the ceiling of the compartment.

Under the central outlet 17 a conoidal shell d is fixed to b, and below it a reflecting-plate 'r is attached by several screws 19 to the casting a. The air that enters by the circular openings c, heated by passing in contact with the hot wall of b and over the heated'shell d, passes by holes e through the plate 1', and additional air enters the globe through holes h to supply the fiat flame s.

Having thus described the nature of this above the burner; substantially as described;

, In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

W. H. I. WELOH.
